Process for producing single crystal of compound semiconductor and crystal growing apparatus

摘要

In a production method for producing a compound semiconductor single crystal by LEC method using a crystal growth apparatus with a double crucible structure, it was made to grow up a crystal by covering the second crucible with a plate-like member having a pass-through slot for being capable of introducing a crystal pulling-up shaft having a seed crystal holding part at a tip into the second crucible and creating a state where an atmosphere within the second crucible scarcely changes (a semi-sealed structure).
